UPW2V221MRD

The UPW2V221MRD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can designed for power‑handling applications. It delivers 220 µF capacitance at a 350 V rating with a compact φ25 × 50L package and 12.5 mm lead spacing.

Engineered for demanding environments, this UPW series part combines long life (8,000 hours at 105°C), controlled loss characteristics, and defined low‑ and high‑frequency ripple current capability to support power conversion and industrial electronic systems.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a 350 V rated voltage and ±20% tolerance, providing bulk energy storage for high‑voltage rails.
• High‑Temperature Endurance — Rated for 8,000 hours at 105°C, enabling sustained performance in elevated ambient and thermal stress conditions.
• Ripple Current Performance — Low‑frequency ripple current of 550 mA (120 Hz) and high‑frequency ripple current of 880 mA (10 kHz), supporting both line‑frequency and switching converter loads.
• Leakage and Loss — Specified leakage current of 3,180 µA and tan δ of 0.2 (measured at 20°C, 120 Hz), giving predictable dissipation and self‑discharge behavior for design margin calculations.
• Robust Mechanical Package — Radial lead can with φ25 × 50L dimensions and 12.5 mm lead spacing (±0.5 mm tolerance) for through‑hole mounting and secure PCB anchoring.
• Automotive‑Grade Qualification — AEC‑Q200 rating, suitable for designs requiring automotive component-level qualification workflows.
• Wide Operating Temperature — Specified for −40°C to 105°C to accommodate a broad range of environmental conditions.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to support production and prototype handling.

Typical Applications

• Switching Power Supplies — Bulk energy storage and smoothing for DC bus and output filtering in high‑voltage converters.
• Industrial Power Electronics — DC link and intermediate bus capacitance in motor drives, inverters, and power modules that require long lifetime at elevated temperatures.
• Automotive Electronics — Power conditioning and energy buffering in qualified automotive electronic control units and subsystems where AEC‑Q200 compliance is required.
• Energy Storage Subsystems — Local decoupling and transient response support for systems with moderate ripple current demands across low and high frequencies.

Unique Advantages

• High‑Voltage Energy Density: 220 µF at 350 V provides substantial stored energy in a compact φ25 × 50L can, reducing the need for multiple parallel components.
• Long Endurance at Elevated Temperature: 8,000 hours at 105°C supports extended field life in thermally challenging installations.
• Frequency‑Versatile Ripple Handling: Separate low‑ and high‑frequency ripple current specifications (550 mA @120 Hz / 880 mA @10 kHz) help designers size capacitors for both line‑frequency and switching environments.
• Automotive Qualification: AEC‑Q200 rating streamlines integration into automotive design flows that require component qualification.
• Predictable Electrical Losses: Specified tan δ and leakage current values enable accurate thermal and reliability margin calculations during system design.
• Through‑Hole Robustness: Radial lead package with defined lead spacing simplifies board layout and mechanical retention for vibration‑prone applications.
